I want a good, low drop with good performance. Is a 2" drop with something like the Sprint springs and Tokico Illuminas going to be good enough, or should I look into coilovers? I'm just a bit skeptical that even if the 2" drop is enough to look good, maybe it won't perform very well.

 

No such thing as a good, low drop. You can be low, but that's not good.

Lower than about 1.5" and you lose too much suspension travel for a comfortable ride and stable handling.
